WOW FACTOR WILL BE KING
World’s largest and tallest engineered timber office building starts to take shape in Queensland
The first delivery of cross laminated timber (CLT) columns, beams and floor panels arrived at the Brisbane Showgrounds in mid-February for what’s set to be the world’s largest and tallest engineered timber office building, 25 King.1 At a height of almost 45 metres, the ground plus nine-storey Bates Smart-designed tower includes services provided by global engineering firm Aurecon as well as three bespoke retail tenancies. Owned by Impact Investment Group (IIG) the innovative building will also be the future home of Aurecon, with the company committing to lease four of the nine office floors. General Manager for Lendlease Building, Tony Orazio said construction of 25 King was well under way with the installation of the first pre-assembled modules taking place. “As the world’s largest and tallest engineered timber office building, 25 King will be one of the most exciting additions ever made to Brisbane’s skyline. “A key element of 25 King’s structure is the use of prefabricated modules for each floor. These modules are preassembled at ground height and then lifted into place to form what looks like a wooden lego structure,” said Mr Orazio. “The fascinating thing about building with timber is that its strength is akin to concrete and steel, it can be produced economically in a factory environment and most importantly boasts a plethora of sustainability benefits.” Queensland’s Deputy Jackie Trad described said 25 King as breaking new ground in its use of structural timber in a building of its type and size. “These materials are sustainable, strong and light, with a structural strength akin to the traditional concrete and steel. “This is a great example of the type of development we’ll be seeing more of in the future, and it puts Queensland at forefront of cutting edge sustainable construction practices,” she said when details of the massive project were released last year. Constructed with wood, CLT has a far lower carbon footprint than other building materials, the production process produces zero waste, and timbers are sourced from certified sustainably managed forests. A world first in sustainable architecture, 25 King is targeting a 6-star Green Star Design and As Built rating which will use 67 per cent less electricity and 55 per cent less potable water2 and is targeting a WELL Core and Shell rating. 25 King will see six storeys above ground by mid-2018 and is due for completion in late 2018, with Lendlease developing and building the asset. Lendlease will continue to work with its partners to lease the approximately 7,900 square metres of remaining office space. 25 King is Lendlease’s fifth engineered timber building in Australia and joins International House Sydney, Forte Apartments and Library at The Dock in Melbourne, and Jordan Springs Community Hub in Western Sydney. Lendlease is a partner in The Future Timber Hub, Australia’s leading timber research collaboration committed to challenging the barrier of timber construction by pursuing research-based strategies and innovation technologies to boost the timber industry.
